SHUKA MINERALS PLC - Kabwe Drilling (KBDD06 and KBDD07) Initial northerly exploration holes confirm continued mineralisation
What this filing means
Shuka Minerals has confirmed mineralisation extends into the previously unmined northern reaches of the Kabwe Speaks/Mine Club orebodies in holes KBDD06 and KBDD07, with KBDD06 returning a standout 6m at 4.57% Zn including peak Zn readings of 21–23% — a genuine exploration hit. The programme has been expanded to 2,500m. The catch is that the share had already run up strongly into the announcement (+18% CAR-20) on the back of a string of prior drilling updates, and these latest grades are acknowledged by management to be lower than the exceptional results from earlier in the campaign, with all figures still unverified by JORC-compliant laboratory analysis.
Shuka has hit mineralisation in two new exploration holes further north at Kabwe — one hole returned a very high zinc reading at a peak of nearly 23%, which is a good sign the orebody continues in that direction. The company has responded by drilling more holes. But the share had already risen sharply over the past month on earlier positive drilling news, and the average grades in these two holes are lower than what was found before. The results also need to be confirmed by a proper laboratory before they can be treated as definitive.
Bull case
- Initial exploration holes KBDD06 and KBDD07 confirm mineralisation extends ~1km NW into the previously unmined northern reaches of the Speaks/Mine Club orebodies, validating continuity of the Kabwe system.
- KBDD06 returned a 6.00m interval at 4.57% Zn with peak readings of 21.05%, 20.84% and 22.80% Zn across 1m of core, showing high-grade persistence even at the exploration front.
- Management extended the drilling programme to 2,500m citing 'excellent results received to date', with KBDD08 already underway targeting more central zones of the orebodies.
- The existing NI 43-101 base — Speaks at 1.944 MT grading 12% Zn / 2% Pb and Mine Club at 0.666 MT grading 11.7% Zn / 0.8% Pb — is a substantial resource target that the current drilling is now intersecting.
Bear case
- All reported assays are unverified portable XRF readings pending JORC/NI 43-101 laboratory analysis, so headline grades remain preliminary.
- Most KBDD06/07 intercepts (1.08%–1.69% Zn) sit materially below the Behre Dolbear indicated/inferred Speaks grade of 12% Zn, casting doubt on economic tenor.
- Management itself concedes the average grades in KBDD06/07 were lower than the exceptional grades seen earlier in the current drilling campaign.
- The drilling programme has been expanded to 2,500m yet the release discloses no capex, cash position, debt, or funding plan for the enlarged scope.

SENS-AI conclusion
An operationally constructive drilling result — mineralisation confirmed in previously unmined northern territory with a high-grade sub-interval that validates the extension thesis. However, the +18% CAR-20 means the market had already celebrated the drilling campaign's trajectory before these holes landed, and management's own caveat that grades here are below the earlier exceptional highs is a real qualification. Useful confirmation for holders; not a fresh re-rating signal for newcomers. The unaudited XRF basis and absent funding disclosure are genuine confidence discounts that prevent a stronger directional call. So what: the resource case is consistent and expanding, but the market needs JORC-verified assays and a disclosed funding plan before the drilling translates into a balance-sheet story.
The JORC-compliant laboratory assay results and a disclosed funding plan for the extended 2,500m programme are where the market will test whether these grades hold up and whether the exploration spend is covered.
Evidence from the filing
Initial exploration holes KBDD06 and KBDD07 confirm mineralisation extends ~1km NW into the previously unmined northern reaches of the Speaks/Mine Club orebodies, validating continuity of the Kabwe system.
“the programme here is much more of a true exploration drilling programme, we again hit mineralisation in our first holes and demonstrated the northerly reaches of the orebodies.”
KBDD06 returned a 6.00m interval at 4.57% Zn with peak readings of 21.05%, 20.84% and 22.80% Zn across 1m of core, showing high-grade persistence even at the exploration front.
“KBDD06 – 6.00m @4.57% Zn from 84.66 to 90.66m. Peak Zn readings of 21.05%, 20.84% & 22.80% occurred across 1m of core.”
Management extended the drilling programme to 2,500m citing 'excellent results received to date', with KBDD08 already underway targeting more central zones of the orebodies.
“the drilling which has now been extended to 2,500m due to the excellent results received to date”
The existing NI 43-101 base — Speaks at 1.944 MT grading 12% Zn / 2% Pb and Mine Club at 0.666 MT grading 11.7% Zn / 0.8% Pb — is a substantial resource target that the current drilling is now intersecting.
“The Behre Dolbear 2023 NI 43-101 report indicates that the Speaks orebody contains 1.944 million tonnes ("MT") of indicated and inferred resource at grades of 12% Zn and 2% Pb. The Mine Club orebody contains 0.666 MT of indicated and inferred resource at grades of 11.7% zinc ("Zn") and 0.8% lead ("Pb") plus silver and vanadium oxide.”
All reported assays are unverified portable XRF readings pending JORC/NI 43-101 laboratory analysis, so headline grades remain preliminary.
“These assays were taken with a calibrated XRF machine and will be verified in due course with JORC/NI 43 101 laboratory analysis and testing.”
Management itself concedes the average grades in KBDD06/07 were lower than the exceptional grades seen earlier in the current drilling campaign.
“the average grade was lower in KBDD06 and KBDD07 than the exceptional grades encountered thus far in the current drilling campaign, the presence of high-grade sections and mineralisation in general in these holes is highly encouraging.”
